Spirit and Crit Rates

[Concillian]

Now, the question I have for you all here is why is the crit rate reported by Damage Meter consistently 4-5% higher than that shown on the tooltip? Araxis has no talent spec that adds crit% to his white damage. It's possible that his +3 daggers skill is affecting things somewhat, but I don't think that would effect the crit% that much (if it did, watch for all rogues to suddenly start equiping +weapon skill items in PvP). I suspect that the difference is in how Blizzard calculates crit rates and how Damage Meter reports crit rates. Misses might be playing a role in one and not in the other, for example. Does anyone have a good explanation of the difference? I want to know in case we do some more tests and use Damage Meter to tabulate data again.

This could be the case. Supposedly the table lookup nature of WoW means that if you have a 30% crit rate you get 30% of all swings as crits regardless of if you miss.

Damagemeters could be recording it as a % of landed blows, not factoring misses into the crit rate. Assuming he has a miss rate of about 14%:
Then you might expect, on average 28 per 100 swings will be crits, 14 will be misses, and the remaining 58 normal hits.

WoW says 28% crit, which is 28 crits / 100 swings = 0.28 = 28%
Damagemeter could be calculating crit rate as 28 crits / 86 landed blows = 0.325 =32.5%

It's even within the realm of what you might expect for DW miss rates.
